Your 1995 Volkswagen Jetta was available in many trim levels -- base, city, GL, GLS, and GLX. The available engines were the 2.0-liter four-cylinder and the 2.8-liter V-6. If you opted for the manual transmission, it was the same five-speed manual in all models.
VW requires the use of SAE 80 API GL-4 gear oil or synthetic transmission fluid G 50 SAE 75-90.
